All python code lives in the ~/Adafruit_Python_GPIO/Adafruit_Python_BME280
directory that was created when the Adafruit BME280 code was unzipped.


From user crontab start BME280 tasks and also use cron to run the wide format
and csv reads along with grabbing the tail of the pressure sensor delta reading.
This helps form the dashboard.
